APPARATUS FOR ADIVIINISTERING ANESTHETICS.

SPECIFICATION forming part of Letters Patent No. 782,108, dated February 7, 1905.

Application tiled November 18,1903. Serial No. 181.648.

To fri/7 H'm'm, if may con/cern.-

Be it known that I, RAYMOND C. Colmax, a citizen ot' the United States, residing at Upper Sandusky, in the county ot' lVyandot and State ot' Ohio, have invented a new and useful Apparatus tor ;\dministering Anesthetics, ot' which the following is a specilication.

lhis invention relates to a novel apparatus t'or use in administering anesthetics, particularly a mixture ot' nitrous oxid and oxygen.

The primary object ot' the invention is to produce an extremely simple and compact arrangement ot parts, enabling' the entire apparatus to be either packed in a small case for transportation and organized t'or instant use or packed in still smaller compass with the parts disassociated, as desired.

A further object of the invention is to equip the apparatus with gas-bags and with means whereby each ot` said bags may be supplied with nitrous oxid or oxygen, as the case may be, t'rom a pluralityv ot` c vlinders or reservoirs, so that upon the depletion ot' the gas in either cylinder the gas will be supplied from another cylinder without the loss ot' time or the necessity for putting a new cylinder in place.

t'urther object ot' the invention is to provide means engaging the opposite ends otl the cylinders to avoid the possibility' ot displacement when the apparatus organized t'or use is carried t'rom one point to another.

Further objects ot' the invention subordinate to those enumerated will appear during the succeeding description ot' the preferred construction illustrated in the accompanying drawings and succinctly detined in the appended claims.

ln the said drawings, Figure 1 is a perspective view ot the apparatus equipped `tor use, j

the tube leading to the inhaler being broken l away. Fig. 2 is a top plan view of the same subject-matter with thc bags and cylinders removed. Fig. 3 is a vertical section ot' the apparatus with the gas bags and cylinders removed and showing some ot' the parts in elevation. Fig. t is a detail view ot' the cylinder-retaining bracket. Fig. 5 is a detail plan 1 view, partly in section, showing the arrangement ot' the cylinder-necks within a pair ot' l ply the bags with gas.

yokes and the manner in which said necks are placed in communication with a bag-nipple.

Like numerals otl reference designate corresponding parts in the several ligures otl the drawings.

The entire apparatus is supported by a baseplate l, upon which is screwed an internallythreaded socket 2 t'or the reception ot' the lower threaded end ot' a detachable standard 3. The stem or standard 2% comprises separable upper and lower sections .JC and 5, having their contiguous ends oppositely threaded for engagement with a coupling' 6, by means ot' which the sections are secured rigidly in axial alinement. The upper section L ot the standard has its upper end threaded t'or a considerable distance and is screwed into the lower side otA a three-way litting T, t'rom which extends in opposite directions a pair otl pipes 8 and 9, connected by elbows or angle lttings 10 and 11 to depemlingl nipples 12 and 13, to which latter gas-bags 1i and lo are designed to be attached permanently in any desired manner. lt may be noted at this point, however, that the gas-bags hang vertically and are ot' proper size to be supported above the base l.

From one side et' the three-way titting T extended a horizontal nipple 16 for the attachment ot' the inhaler-tube 1T, designed to convey the gas t'rom the bags le and 15 to the inhaler. (Notshown.) The liowofthegasfrom the bags is regulated by controlliiig-valves 1S and 19, located in the pipes 8 and t), preferably adjacent to the litting T, and operated by comparatively small hand-wheels 2O and 2l, the upper edges ot.l which do not project above the valve-casing'. Asis well understood by those skilled in the art, the nitrous oxid and the oxygen are supplied in standard carboys or cylinders which in practice constitute a part ot the apparatus and are arranged to sup- Vl n the illustrated embodiment ot' the invention I make provision tor the use ot' t'our cylinders, the nitrous-oxid cylinders being indicated by 22 and 23 and the oxygen-cylinders by Hand These cylinders are grouped around the standard 3 in close proximity thereto, and their dischargenecks 26 are received within yokes 27, 28, 29, and 30 and retained by set-screws 31, as usual. The several yokes are formed at the outer ends of arms 32, diverging from a hub 33, having a threaded opening 34 for the reception of the threaded upper end of the upper standard-section 4. (See Fig. 3.) The hub 33, the arms 32, and the several yokes are preferably formed in a single casting, which constitutes a yoke-frame located immediately below the pipe connections leading from the nipples 12 and 13 to the inhaler-tube.

Adjacent to each of the nipples 12 and 13 is located a three-way union 35, having connection with a nipple through a short pipe 36, and likewise in communication with the adjacent pair of cylinders through the medium of angularly-disposed pipes or conduits 37 and 38, the remote ends of which are screwed through the proximate sides of a pair of yokes and have their extremities extended into the discharge-necks of the cylinders. The pipes 37 and 38 are equipped with cocks 39 and 40, by means of which either of a pair of cylinders may be placed in communication with a gas-bag Yto supply the latter with gas. It

` should be noted at lthis point that the radial disposition of the arms 32 of the yoke-frame disposes the yokes in angular relation, this being a material feature, since it permits the pipes 37 and 38 to converge at the union 35, arranged in proximity to one of the gas-bag nipples, as already described.

We have now seen that each gas-bag is arranged to be supplied from either of a pair of storage-cylinders and that both bags discharge into a common inhaler-tube through conduits equipped with controlling-valves, whereby the proportion of nitrous oxid and oxygen supplied to the patient may be properly regulated. It also follows from the described arrangement that upon the depletion of one cylinder the gas-bag may be supplied immediately from another cylinder, since it is only necessary for the operator to turn one of the cocks 39 or 40 in order to establish communication between the bag and a new source of supply. This is highly advantageous for the reason that should the supply of nitrous oxid be prematurely exhausted the patient would recover from the anesthesia before another cylinder could be attached in place of the one exhausted. Similarly, if the supply of oxygen should give out the patient would be in danger of asphyxiation before the exhausted cylinder could be replaced by one containing a new supply of oxygen.

As has been premised, one of the primary objects of this invention is to group the entire apparatus in very-small compass, so that it may be carried from place to place in a small case and completely set up for instant use when removed from the case and supported thereon or upon a table or the like. It will be seen by reference to Fig. 1 that all of the parts are arranged compactly over a small base, designed1 to lit in a case the top of which is located in a plane just above the horizontal pipe. This pipe constitutes aconvenient'handle, by means of which the apparatus may be lifted from its case and carried about. Byexercising reasonable care the cylinders, being securedat their upper ends within the yokes, will remain in their proper positions during the transportation of the apparatus; but in order that their rigid retention in proper position may be absolutely insured I preferably employ what may be termed a cylinder-retaining frame 41, comprising a hub 42, vertically adjustable upon the standard 3, and a series of cylinder-receiving rings or sockets 43, having shanks 44 radiating from and screwed into the hub 41. (See Fig. 4.) In order to prevent the turning of the Shanks 44, the latter are preferably provided with lock-nuts 45. The cylinder-retaining frame is designed to be held in its adjusted positions by a clamping-screw 46, screwed into the hub and designed to bear against the standard 3. In attaching the cylinders their' lower ends are passed into the rings 43, the frame being adjusted in its proper position upon the standard, and the cylinders are clamped within the rings by the clampingscrews 47, one of which is passed through each ring for engagement with the cylinder encircled thereby. The cylinders positioned in the manner described are rigidly secured to the standard by connections at their upper and lower ends, and the entire apparatus, organized for instant use, may therefore be conveniently carried without liability of derangement. A further distinct advantage of the particular organization described resides in the separability of its various parts to facilitate its being packed in still smaller compass4as, for instance, in a suit-case. Af-

IOO

ter removing the cylinder the superstucture grouped upon the upper section of the standard may be detached by unscrewing the upper standard-section from the coupling. The lower section of the standard may then be unscrewed from the socket, the cylinder-retaining frame removed from the standard, and if it is not desired to transport the base the socket may be removed from the latter and subsequently reattached to a table or other support when the apparatus is to be assembled for use. In some instances also I contemplate the attachment of the standard to a suitable folding support or stand, which, however, is not illustrated or specifically described, for the reason that it does not constitute a part of my present invention.

It is thought that from the foregoing the construction, operation, and many advantages of my improved apparatus for administering anesthetics will be apparent with- IIO out further description; but while the present embodiment ot' the invention is thought at this time to be preferable l desire to be understood as reserving the right to eir'ect such changes. moditications, and Variations ot' the illustrated structure as may 't'all Vfairlj within the scope ot the protection prayed.
